Vice President Joe Biden laughed and made the sign of the cross when asked to share his thoughts on the first presidential debate in his first appearance on "The Tonight Show with Jimmy Fallon" on Monday night.

"I've never seen anybody who knew as few facts," Biden said of Trump's performance. A chuckle from Fallon prompted Biden to say, "You know, it's not a joke." The vice president then warned the audience he will turn serious for a moment to talk about the election.

In the days following the first presidential debate, Donald Trump has continued to argue that he performed well and Hillary Clinton continues to struggle with millennial voters. Host Seth Meyers looks at these developments while also commenting on Independent candidate Gary Johnson’s inability to name a world leader he liked or admired.

"What does it make the rest of us? Suckers?" Biden said. "Can you think of any president, any president that you have studied read about or knew, who who would say anything like that? Name me one president who would do that. It angers me quite frankly."

He continued, "It's one of the things that the American people really resent. The American people don't like being played for suckers."I can't imagine why somebody would say that makes me smart."
